Problems solved by technology

In this way, due to the pasting process, adhesive or rainwater penetration, the insulation board of the external wall is separated and falls off from the building wall, which seriously affects the quality of the project; moreover, when the insulation board separates or falls off, it must be It is necessary to remove all insulation boards and tile walls and paste them again, resulting in huge economic losses

Embodiment 1

[0030] Example 1: Reinforcement of filled walls

[0031] 1. Outside the separated insulation layer 3, use a portable cutting machine to cut along the joints of the pasted tiles into an "I" shape, and the depth shall not damage the fiber mesh of the inner layer of the tile.

[0032] 2. After the above process is completed, use a φ8 extended drill to penetrate the wall, and then use a portable cutting machine to cut an inner groove with a depth of 1cm, a width of 2cm, and a length of 6-8cm, and then insert the long rivet 3 along the "work ” font cutout, and use supporting tool 4 to tighten it after passing through the wall. Then put into two φ 6 round steel heads 5 of about 3cm long in the inner groove, and the round steel heads 5 and the tensioned long rivets 3 are welded together by electric welding. At this time, the reinforcement task is completed.

[0033] 3. Remove the supporting tool 4 and use it again, cut off the excess part of the exposed wall with a cutting machine,...

Embodiment 2

[0036] Example 2: Reinforcement of concrete walls

[0037] 1. Outside the separated insulation layer 3, use a portable cutting machine to cut along the joints of the pasted tiles into an "I" shape, and the depth shall not damage the fiber mesh of the inner layer of the tile.

[0038] 2. Use a φ8 extended drill bit to drill holes along the tile seam of the outer wall to the concrete wall 6. Clean the dust in the hole, implant the chemical anchor bolt 7 of φ8, and after it is completely solidified (reaching the standard strength), use the supporting tool 4 to reinforce and tighten it, and the separation wall will be completely reset. Use the same method to implant short rivets 8 around the periphery.

Abstract

The invention relates to an outer wall strengthening rivet and an outer wall strengthening method. The outer wall strengthening rivet is composed of a rivet nut and a rivet rod, and is characterized in that the rivet nut is in an H shape. Under the situation of not damaging the wall or a heat preserver, outer wall heat preservation layers which are separated and fall off are reset through the outer wall strengthening rivet, the technical defects that the outer wall heat preservation layers are completely eradicated and pasted again in the prior art are overcome, separated heat preservation boards are strengthened and maintained, and then maintenance cost is lowered.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to an exterior wall reinforcement rivet and an exterior wall reinforcement method. Background technique [0002] At present, the exterior wall of the building is insulated with phenolic board A-class fireproof material. The phenolic board A-class fireproof material is pasted on the exterior wall of the building with an adhesive. In this way, due to the pasting process, adhesive or rainwater penetration, the insulation board of the external wall is separated and falls off from the building wall, which seriously affects the quality of the project; moreover, when the insulation board separates or falls off, it must be It is necessary to remove all the insulation boards and tile walls and paste them again, which will cause huge economic losses. Contents of the invention [0003] The purpose of the present invention is to overcome the defects of the above-mentioned p...
